To all whom it may concern: In Fig. 1 the base 1, preferably of cast Be it'known that I, THOMAS E. MOLDON, iron, is provided with bearings 2 and '3 citizen of the Dominion of Canada, and a adapted to carry the shaft 6 which is proresident of Toronto, county of York, and vided with a driving pulley 5, the spur gear 5 Province of Ontario, Canada, have invented 7 and a simple form of clutch 60, which is a new and useful Improvement in Coillikewise adapted to receive and support the Winding Machines, ofwhich the following mandrel 61, which in turn carries the spool is a specification. por bobbin 12 upon which it is desired to My invention relates to machines for wind the wire or strand. An auxiliary base 19 winding strands of material such as wire, member 13 is provided and secured to the thread, ribbon or filaments, into coils. helimajor base 1, and serves as a bearing for n. cos or bobbins, and pertains specifically to driven shaft 9, one extremity of which is machines for winding copper wire into eleccarried by the bearing member 3. The shaft trical coils or helices for use in electrical 9 carries a spur gear 8 meshing with spur, apparatus, gear 7 and united to a bevel gear 19. The The object of my invention comprises bevel gear 19 turns with spur gear 8 and producing a machine in which the 'transboth turn loosely on the shaft 9. A bevel verse or lateral feed for the material being gear 45 is pivoted in a support 50 and wound may be altered without necessitating meshes with bevel gear 19 and likewise with changes in gearing or cams, in order that bevel gear 20 carried by, but adapted to rothe machine may be quickly and easily tate loosely on shaft 9. Between the bevel adapted to wind various sizes of wire or gears 19 and 20 there is provided as shown other material. in Fig. 4, a double cone clutch member 4.8, I accomplish these and other desirable which is splined to the shaft and is free to 25 features which will hereinafter be pointed slide thereon, as shown in Fig. 4. A split out and discussed, by means of the novel ar ring 60 is carried in a channel in the memrangement illustrated in the drawings and her 48 and is provided with a pin 44'extenddescribed in the accompanying specification. mg through a slot 24 in the reversing lever Q In the drawings which accompany and 26. one extremity of the lever 26 is pivoted 35 form a part of this specification, and inby means of the pin 25 in the bearing memwhich like reference numerals designate corber 50, the other extremity of which is proresponding parts throughout; vided with a pin 23 encircled by a spring Fi 1 is a plan view of a simplified form member 22, the other extremity ofwhich is 35 of winding mechanism incorporating my artlculated with a pm 21 carried by a shaft 5 novel device. 14 for a purpose which will hereinafter be Fig. 2 is a front elevation of the same. described. Fig. 3 is a sectional view taken on the A follow nut 32 is carried by the threaded line 3-3 of Fig. 2. 7 portion of the shaft 9, and as shaft 9 is Fig. 4 is a partially sectioned enlarged driven, traverses the shaft from left to right View of a detail of the reversing mechanism. or irom rlght to left dependent upon the Referring now specially to Figs. 1 and 2, direction of rotation of the shaft. As I have chosen to illustrate mv novel device shown in Fig. 3, this follow nut is given a as incorporated in an extremely simple form shape such as to encircle and slide on shaft of winding machine, as my invention is in- 14, between adjustable stops 17 and 15. (101- dependent of the particular form of driving lars 18 and 16 are provided on shaft 14 to or reversing mechanism. and may be used limit the lateral motion of the shaft. It in conjunction with many various forms of will be obvious that as the follow nut 32 is driving and reversing mechanisms. Theremoved either to the right or left during the fore, while it is necessary to enter into some operation of the machine, at each extreme detail in describing even the simple revers- 0, its motion, it will engage with sto 17 Eng mechanism shown, it is understood that .or 15 to propel shaft 14 to the ri ht or left no claim is made to that part of the device. and these stops are set in accor ance with the width of the-winding desired. The lateral motion of the shaft 14 causes a reversal of the direction of the motion of the follow nut 32, because as pin 21 is carried to the right or left of the center line passing through pin 23, and the pivot point of the lever 26, the lever is moved to theright or left as the case may be, and such-motion results in bringing the edges of slot 24 against pin 44 with a sharp impact to declutch the clutchcone 48 from one of the bevel gears and causes it to engage the other of the pair to cause. a reversal of rotation of shaft 9, and hence a reversal of the lateral motion of follow nut 32.

The guide rod 10 is carried inbearings provided in the auxiliary base 13 and is adapted to move laterally therein. The guide rod 10 carries at one extremity a wire or filamentguide 11 composed of a pair of deep grooved pu leys maintained in a support which is securely attached tothe rod 10.

A supporting rod 27 is securely attached to a boss formed on the auxiliary base 13, and is maintained with its longitudinal axis at right angles to the longitudinal axes o The rod 27 carries a bearing support-28 adjustably secured to the rod near 1ts free extremity by means of the clamping nut 52. A sleeve bearing is mounted on the bearing support 28 and is retained in a rotatable manner by the pointed set screw 51 as shown in Fig. 3. The-sleeve 55 serves to slidably support one extremity of a pantograph rod 29, the other extremity of which is pivots ally mounted by means of the block 71, and the shouldered screw on the follow nut 32 as indicated in Fig. 3.

A slotted adjustment member 30 is secured by means of a set screw 53 to the guide rod 10. The attachment of the member 30 with the guide rod. is preferably made when the follow nut 32 is at the midpoint of its travel on the shaft 9. The guide rod 10 is then moved so that the wire guide 11 is in line with the mid point of the coil or bobbin to be wound. and the slotted member 30 is then clamped to the guide rod 10 at a point midway between the supports for the rod in the auxiliary base member 13.

A clamping nut, the stem 48 of which is rigidly united with a sleeve 47, which is ations shown on the member 30 in Fig. 1.

It will be observed from the foregoing that as the follow nut 32 traverses the threaded shaft 9 in the operation of the de-' vice,,the pantograph rod 29 will be swung about its pivot point 55 with the support rod 27, and that further the guide rod 10 will be moved a distance to the right or left, which is dependent upon the position of the clamping nut 48 with regard to the slotted member 30. It being readily understood that as the clamping nut 48 is moved upward in the slotted member 30 as viewed in Fi 1 the travel of the guide rod 10 carrying t e wire guide 11 will be shortened for a given length of travel ofthe follow nut 32, and therefore the travel of the wire guide with relation position of the clamping nut '48 with respelct to the slotted member 30. It is obvious,"

f ther, that if the slotted member 30 be calithe'shafts 9 and 14, and of the guide rod 10.

brated for various sizes of wire, that it may be graduated so that the machine may be quickly, simply and easily adjusted to wind various sizes of wires or filaments. It will be obvious further, that the stops 17 and 15 upon the reversin shaft 14, may be positioned to wind various width of coils. It is further obvious from this discussion, that my invention, which relates to the mecha nism for quickly and easily adjustin the machine to wind various diameters o filament, may be incorporated to function with machines employing many different types of reversing or driving mechanisms. It will be further obvious that the length of the slotted member may be increased to give the machine a wide latitude of adjustment.

While I have illustrated and described one simple embodimentfif my machine, it should be clearly understood that I may vary the details thereof, without departing from the spirit or narrowing the scopevof my invention.

Having thus completely described my in-' vention, what I claim as new and desire to secure by United States Letters Patent is as follows 1. A coil winding mechanism comprising,

a bobbin, means for rotating said bobbin, a

filament guiding means adapted to be moved laterally with respect to said bobbin, a screw for moving said filament guiding means,a
